"Two prototype models of an unusual gaming laptop with three screens have been stolen at the CES tech show in Las Vegas, according to PC maker Razer. The concept device boasts three 4K screens and is said to be the first portable laptop of its kind. Razer said the laptops had gone missing from its booth at the tech show on Sunday.

The incident was being taken 'very seriously', said chief executive Min-Liang Tan. A Razer spokesman said it was offering $25,000 (£20,600) for any 'original information leading to the identification, arrest and conviction' of those allegedly involved in the crime."
